Olmsted County (County Road 7 bridge replacement) - 401 Water Quality Certification
We invite you to comment on the draft 401 Water Quality Certification for the Olmsted County Road 7 bridge replacement.
The Olmsted County Public Works Department proposes to replace the bridge adjacent to U.S. Route 52 that carries County Road 7 over an unnamed creek that flows into Mill Creek. The bridge will be replaced with two precast concrete box culverts measuring 14 feet wide, 9 feet high, and 92 feet long. The project will place riprap inside both culverts and at their apron ends. The project will impact a total of 198 linear feet of the creek, but with no permanent impacted wetlands along the creek, mitigation is not required. The water quality is not expected to change and may improve following project completion.
A 401 Water Quality Certification is required when an individual, business, or property owner proposes construction-related activities near a navigable lake, river, stream, or adjacent wetland. The MPCA reviews projects to ensure they will not violate Minnesota's more protective water quality standards. The 401 certification becomes an enforceable component of the associated federal license or permits issued under the Clean Water Act.
